The version of aMember that we are currently using stores passwords as plain text, we are currently in the process of moving the site to aMember 4, but since the initial migration more users have been added to the current live site (aMember 3). I'd like to just migrate the new users, is there an easy way to do this? Alternatively I can create a script to migrate the user table from 3 > 4 fields, but I'd need to know the encryption formula for the passwords, an someone provide this please? many thanks.
You can run migration script again (discard all steps besides users). Script will import only new users. aMember 4 uses PHPASS to hash passwords - http://www.openwall.com/phpass/
